(a) Transpirational pull is demonstrated by this set up.
(b) Constant air blowing will increase the rate of transpiration so , level of water will go down.
(c) The mercury level will go down, if phenyl mercuric acetate is sprayed on leaves.

A cyclindrical ice block is floating in water 10% of its total volume is outside water. Kerosene oil (relative density=0.8) is poured slowly on top of water in the container. Assume that the oil does not mix with water. Height of the ice cylinder is H. (a) As kerosene is poured, how does the volume of ice block above the water level change? (b) What is the thickness of kerosene layer above the water when 20% of the volume of the ice block is above the water surface? (c) Find the ratio of voume of ice block is kerosene to its volume in water after the kerosene layer rises above the top surface of ice and the block gets completely submerged. Neglect any melting of ice.

(i) A toy boat made of steel is floating in a beaker having water. The beaker is placed on a spring balance. The boat tilts and sinks into water. (a) Will the level of water in the beaker go up or fall down? (b) Will the reding of spring balance decrease or increase? (iii) You are in a boat on a calm lake. There is a floating log near you . You pick the log and put it into the boat. What happesn to the level of water in the lake? Does it rise or fall?

In a village, farmers started cultivating crops all around a lake which was always filled with water. They added lot of materials W to the soil in their fields to increase the yield of crops. Soon they found that the whole surface of water in the lake was covered with a green layer made up of tiny organisms X. After some time, the fish present in the lake started dying in large numbers they could not get sufficient Y due to a process Z which had occurred in lake water and drained out all the Y present in the water of lake. (a) What do you think materials W are ? (b) Name (i) X, and (ii) Y. (c ) What is the process Z known as ? (d) What happens during the process Z which uses up all the Y present in lake water ? (e) What does this example tell us about the use of materials like W ?
